count of the Revolution it finds in all its Parts, 
while its Forces are otherwife employ’d, and the 
Collc&ion of vegetating duClilc Matter it had ac-

quir'd by plentiful Diet, now as plentifully exube- 
rates to form the Parts of the Butterfly. Thefe 
Truths I am the better acquainted with, becaufe I 
- have particularly examin'd all thole Subftances: You 
cannot tear off a Portion of the Butterfly’s Wing, 
even while in the Chryfalid, but you will find it 
in an Embryo-State, and the Matter which extra- 
vafates upon your ObjeCt-Glafs, if mixt with a little 
Water to preferve its Fluidity, will almoft immedi- 
ately vegetate into thefe microfcopical Productions. 
This argues an extreme Activity in it 5 from Activity 
follows ACtion, and an EffeCt, which can be no 
other than the Formation of the Wing it was con- 
tain'd in. 
§ 34. Without infiancing in many other Exam- 
ples, where, by reafoning from thefe Principles, I 
was invariably conducted to certain Confequenccs, 
this laft fufficiently leads to the Nature of animal or: 
vegetable Semen. Thefe latter are Subftances of the 
fame fort, but more exalted, and from thence adapted 
to a prompter Vegetation. Of this kind alfo, but not 
fo exalted, was the gelatinous Subftance 1 obtain’d by 
common Infufions. 
The Exaltation however of Matter does not flop 
here} the lower I purfued this new Clafs of Beings 
in its Defcent, the lefs was this vegetating Force 
clogg'd with refilling Matter, the fvvifter was the 
Motion of the Bodies, and the higher the Degree of 
Exaltation that produc'd them. This inclines me 
to believe, that an animal Subftance may be exalted
